SAMUEL A. DONALDSQN, OF PHIL CAMPBELL, ALABAMA.

SW'INGLETREE.

To all whom it may concern Be it known that l, SAMUEL A. Donuts- SON, acitizen of the United States, residing at Phil Campbell, in the countyof Franklin and State of Alabama, have invented new and usefulImprovements in Swingletrees, of which the following is a specification.

This invention relates to an improvement in swingletrees andcontemplates the provislon 01' swingletree adapted, particularly, foruse upon vehicles which are employed in agricultural pursuits.

It is an object of this invention to provide a swingletree having meansto receive an insecticide, and means whereby the insecticide ma bedistributed upon vegetation.

Another and more detailed object of the invention is the provision ofinsecticide distrihuting means upon the swingletree which willefficiently distribute the insecticide upon vegetation of various types,and will operate etliciently no matter to what height the vegetation maygrow.

lhe above and other objects of a more minute and obvious character,which will become apparent as the description proceeds, are attained bythe provision of a swingletree having a storage chamber therein forcontaining an insecticide and having a drip opening whereby theinsecticide may gravitate upon the vegetation. More specifically theinvention contemplates the provision of an absorbent member adapted tohang from the swingletree so as to engage the vegetation and position itso as to be saturated with the insecticide that flows from theswingletree.

Referring to the accompanying drawings, wherein there is shown one formof device in which the invention may be embodied,

Figure 1 is a plan view,

Fig. 2 is a longitudinal cross-section, and

Fig. 3 is an end elevational View.

. In the drawings, 10 indicates a swingletree provided with the usualcenter eye 11, by means of which the swingletree may be connected to thevehicle, and also having attached thereto the customary end eyes 12formed upon bands 13 which encircle and are secured to the body of theswingletree. T he swingletree is shown as being hollow throughout so asto provide an interior storage chamber 14 into which a suitableinsecticide may be placed. At each end the swingletree may be internallythreaded as at 15 and fitted with a plug 16 which is pe- Specificationof Letters Patent.

ripherally threaded at 18 so as to be removably positioned in the end ofthe device. The plug is formed with a central bore or passage 19extending therethrough, and also has a plurality of supplementalpassages 20 which are radially positioned with relation to the centralbore, and may be opened and closed, as desired, by means of a cap 21 athe plug and adapted to be brought to and from registry with the lattermentioned openings by rotation of the cap.

In order to eiiiciently saturate the vegetation with an insecticideplaced within a swingletree, a length of absorbent material 25, formedpreferably from a number of loose strands, are placed within the plug soas to extend into the hollow body of the swingletree and to hang looselyfrom the end of the swingletree so as to engage the vegetation uponwhich the insecticide is to be distributed. Obviously, the absorbentmaterial may be of any length desired, and may be adjusted in theopening so as to hang for any suitable distance from the swingletree,the length of the material hanging from the swingletree' being dependentupon the height to which the vegetation grows;

In using the device the chamber 14 may be filled by removing one of theplugs which, subsequent to the filling operation, is replaced, and eachof the wicks are adjusted to the desired height. Since the wicks do nottightly fit within the openings 19 it will, generally, be found that asuflieient amount of the insecticide will flow through this opening tomaintain the wicks, at all times, thoroughly saturated. If, however, itis found desirable to increase the amount of insecticide upon the wicks,the cap 21 is adjusted so that additional amounts may flow through theopenings 16 and drip upon the wicks.

It will be understood, of course, that the device shown in theaccompanying drawings and herein described in detail is merelyillustrative of the invention. and that such modifications may be madetherein as come within the scope of the following claims.

I claim: 1. A swingletree havmg means for containing a quantity ofinsecticide, and a drip 7 insecticide, a drip opening through which theinsecticide may flow, and an absorbent member connected to saidswingletree in sition to be saturated by LhE insecticide flowing throughsaid opening and to engage vegetation.

4L. As an article of manufacture, a sWingletree having a chamber thereinfor the reception of an insecticide, a, drip opening, and an absorbentmember in said opening having a portion extending into the insecticidechamber and another portion hanging freely to engage vegetation.

5. A swingletree having an insecticide reservoir therein, a drip openingin one end thereof, and a length of absorbent material extending throughsaid opening into said chamber and hanging from the end of theswingletree to engage vegetation.

6. A. hollow swingletree adapted to receive an insecticide therein andhaving a drip opening in one end'thereof, a length of absorbent materialextending through said opening into the swingletree and hanging from theend of the swingletree, said swingletree having a supplemental dripopening adjacent said firstmentioned opening, and

'means for opening and closing said supplemental opening as desired.

7. A hollow swingletree having a plug removably secured in the endthereoi, said his havin a central bore extendin therethrough,supplemental passages extending through said plug and radially disposedwith relation tosaid central bore, an absorbent member in said herehanging freely from the end of the swingletree and extending into theinterior of the swingletree, and means for opening and closing saidsupplemental passages When desired. In testimony whereof I nave hereuntoset my hand. 7 H
